Nice, but...

What a pity. This kind of puzzle is very nice but the ipad release has a shameful interface. Unusable.

Too many taps for cell filling. Color selection evrytime. Why?

Background color is white. Unfilled cells are light gray. Selected row/column are medium gray. They mix each other! What about a simple X for background cells, for example?
